I'm curious, how many people are aware of these sounds. I have designed, etched, and built my own switching power supplies along with winding my own transformers. I am aware of the source of the noise. So, does anyone else hear these high frequency sounds regularly?

I can’t of anything that makes an unwanted sound. Old CRT TVs used to, but I haven’t used one in years. My monitor at work makes a sound when it turns on or off (I believe there’s an ass-old fuse in there), but it makes no sound otherwise.

I’m still young and hear very well, as exemplified by my annoyance of half-closed bottles of carbonated drinks, which do make a sound.

I did a lot of stuff with CRT’s during ‘Rona and man sometimes that whine just pierced my ears - my dog (RIP love ya bud) would just look at me and slowly walk off every time lol

  • Belkin travel surge protector
  • 5-port USB hub
  • wireless charger

Thankfully none else!

I did when I was younger but I don't hear it since I hit around 30

Yes, but generally only bad quality loud ones.

Yes, but a bit less as I've aged probably because the higher frequency hearing we have starts to diminish the older we get.

I hear some of them. There's a real cheap one my parents got with a security camera thats real loud to me, but they don't hear it.

I used to think I do, but I convinced myself I have a tinnitus.

Since I got older this got better. One benefit I guess?
